memorycopy
Memorycopy refers to the operation of copying a contiguous block of memory from a source address to a destination address without interpreting the data. It is a low-level primitive used to move raw bytes and is a common building block for higher-level operations such as string handling, buffering, and data serialization. In many programming environments the operation is exposed by a standard library function often named memcpy or Buffer.BlockCopy, depending on language and runtime.
Typical signature in C is void *memcpy(void *dest, const void *src, size_t n); it copies exactly n
Performance is highly optimized; modern libraries use architecture-specific instructions and non-temporal stores to maximize bandwidth. The
Care is needed to ensure the specified memory regions do not overlap for memcpy; ensure the correct
Memorycopy is a fundamental operation across systems, embedded, user-space libraries, and kernel code, forming the basis
